Airalo

Choose coverage for the whole itinerary before comparing the smallest headline price. A local package and a regional package answer different needs, especially when crossing borders. The package's data quantity and validity period need to fit both the trip length and expected use. For an allowance-based package, expiry or using all the data ends the package, whichever happens first.

Check device compatibility before buying. Your device must support eSIM and be network-unlocked. Installation needs an internet connection, so plan it while you have one. Read the package's validity policy first: most plans begin when the eSIM connects to a supported network in the destination, but some begin as soon as you install it, even before arrival. When ready to connect, turn the eSIM on and select it for mobile data.

Two package details affect what you can do later. Only rechargeable eSIMs support top-ups, which appear under My eSIMs after purchase. The Plan Type tells you whether the package includes ordinary calls and SMS: Data Only does not, while Data, Voice & Text does. Internet calling and messaging apps can usually use the data connection. Airalo also says that local packages with calls and texts restrict those services to the coverage country. Check these details before relying on a package for telephone calls or text messages during the trip.
